Method for manufacturing adsorption agents containing carbon and endowed with elementary sulphur and method for purifying waste gases by using such absorption agents

摘要

Preparing adsorption agents containing carbon doped with elementary sulfur, comprises mixing sulfur with the adsorption agent, heating the mixture at 120-150[deg]C and retaining the temperature over a period of 0.5-1 hour, where the heating of the mixture takes place under controlled oxygen-containing atmosphere. An independent claim is included for cleaning exhaust gas under use of an adsorption agent doped with elementary sulfur, comprising alternately carrying out the adsorption and desorption of mercury over the exhaust gas system, preferably by at least a packed bed adsorbers.
